A switching adaptive controller for the reduction of commutation torque ripple in BLDCM drives
, 2017 A switching adaptive controller with commutation delay compensation is proposed to control the torque output and to reduce commutation torque ripple in uncertain brushless DC motor (BLDCM) drives. After deriving the error dynamics, the conduction and commutation periods of the drive is taken into account separately, and two different controllers are ...
